It slows us down from our daily rhythms and speed of life. It requires you to mentally engage with your breathing and movement. It slows down the “monkey mind” of busy thoughts. Allowing you to focus and become rested.
Slow movement actually allows blood flow to increase. And increased blood flow means more nutrients are being carried to the brain. And when the brain gets all the nutrients from the blood - oxygen, minerals, etc. You can expect sharper mental clarity, increased focus, and improved memory.
Slow movement increases your parasympathetic (rest and recovery) branch of our nervous system. It’s integral for healing to occur.
